+# Sketchviz Docker
+
+Inspired by `sketchviz.com` (although unaffiliated).
+
+This container bundles Graphviz, a script using [RoughJS](https://www.npmjs.com/package/roughjs) to "draw" the graphs, then tooling needed to convert from `SVG -> PNG`.
+
+Tested with BitBucket Pipelines, see [example script](examples/build_diagrams.sh).
